SilencerCo Fixed Barrel Spacer - Osprey/Octane Series

SilencerCo Fixed Barrel Spacer - Osprey/Octane Series

The SilencerCo Fixed Barrel Spacer is an essential component for running suppressors on firearms with fixed barrels, such as rifles, pistol‑caliber carbines, and submachine guns. When using a suppressor that normally relies on a piston and booster spring for tilt‑barrel operation, this spacer replaces the spring to create a rigid, reliable interface—preventing unnecessary movement and ensuring proper function on non‑tilting barrel systems.

Built from heat‑treated 17‑4 stainless steel, the spacer offers exceptional strength, corrosion resistance, and long‑term durability. It is required when using pistons on the Osprey 2.0 and is fully compatible with both the Osprey and Octane suppressor families. If you’re running a suppressor on a fixed‑barrel platform, this spacer ensures safe, consistent, and dependable operation.
